The Guardian NG DC infrared gas detector supplied by Edinburgh Sensors offers near-analyser quality continuous sampling, measurement and display of CO2 concentrations between 0 – 3000ppm by volume from low voltage DC supplies in the range of 18-30V.
Gas Detectors measure and detect a wide range of gases. Our Guardian NG DC Gas Detector can also be used for CH4, CO measurement. The equipment is set up to measure single use gases at a time.
Send us your samples, and we can measure them live in an online demonstration
